ELECTRICAL CIGAR-LIG HTER.

:SPEGIFIGATION forming part of Letters Patent No. 538,272, dated April 30, l 895.

Application filed August 27, 1894. Serial No. 521,489. (No model.)

To all whom it may concern.-

Be it known that I, HENRY G. ONEILL, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Electrical Cigar-Lighters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention, appertaining to the art of heating by electricity is designed to provide a device for lighting cigars, or tobacco in any other manufactured form, electrically.

The construction is such as to prevent the ashes of the ignited tobacco, from accumulating upon and remaining in contact with the resistance employed as the source of heat, thereby obviating the danger of fusion of the heated wire, incident to contact with ashes containing potash, by naturea flux. The construction also provides a ready and simple means for renewing the resistance, it opencircuited from any cause.

In the accompanying drawings, Figure 1 represents a longitudinal central section through a cigar lighter embodying my invention. Fig. 2 represents a cross section through the same taken just in front of the push button. Fig. 3 represents an elevation of the mouth or lighting end of the cigar lighter.

In the said drawings A designates a suitable hollow handle, or holder divided into two longitudinal sections, A and A and fastened together by screws, or other means. Within the handle are binding-posts, X and X, for the terminals of the feed wires B and B, connecting the feed wires to the flat springs S and S', which form the springs, and one set of terminals, of a two pole push switch; contact plates E and E arranged to underlap the ends of the said springs respectively being the other two terminals of the switch.

F is a push button connected to a bar of insulating material F', arranged so that pressure on F, moving F, the springs S and S are brought into electrical contact with E and E, respectively. On releasing F, the spring action of S and S causes them to recede from E and E, thus breaking the circuit in two places simultaneously.

Y. Y and Z. Z. are binding-posts permitting connection to be made by means of short wires G2 G between E and G, and E and G, thereby forming an electrical conductor to the terminals Y and Y, on the ring L (made of porcelain, or other fireproof insulating material). These terminals Y and Y are so constructed that upon placing the ring in position and fastening by the screws X and X or by any other simple means, a conductor stretched from Y toY will form part of the electrical circuit,capable of being closed oropened by the switch, operated by push button F.

Upon the supporting ring L, I place small projections or, enabling the resistance wire R to befirmly held in place, its ends being connected to the terminals Y and Y.

Beneath the ring L is a mica sheet T, to catch the ashes and prevent them falling into the interior of the handle A. Means are provided, by apertures, to prevent an accumulation of ashes, by allowing them to fall out at the sides, below the ring L.

It will be noticed that the method of supporting the resistance wire, across the aperture of a ring, allowing it to touch on but few points, prevents loss of heat from the wire by conduction, as well as keeping the wire out of contact with the ashes that drop below. The wire from which this resistance is made, must necessarily be non-oxidizable, and of a high fusing point.

G G designate two bars or plates of conducting material fixed removably within the mouth of the said handle or holder at opposite points thereof.

What I claim as new, and desire to protect by Letters Patent, is the following:

1. In a cigar lighter, the combination of a hollow handle with conductors forming part of an electric circuit and extending within the same, springs S S connected to the said conductors, a pair of contact plates, a switch bar and button arranged to press the said springs into contact with the said plates for closing the circuit, a resistance extending across the mouth or open end of said handle,

necting the said terminals to the said bars or plates, a ring of insulating material attached removably to the forward ends of the said bars, a resistance extending across the said ring, and binding posts connecting the ends of the said resistance to the said bars sub stantially as set forth.

In testimony whereof I alfix my signature in presence of two witnesses.

HENRY G. ONEILTJ.
